Hello, and welcome to Wikipedia. I noticed that you made a change to an article, PQS (chemical), but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you!

Hello, and thank you for your recent contribution. I appreciate the effort you made for our project, but unfortunately I had to undo your edit because I believe the article was better before you made that change. Feel free to contact me directly if you have any questions. Thank you! William2001(talk) 00:37, 9 March 2017 (UTC)
